Abstract

PURPOSE:To transfer works in line without disturbing the order, by taking out a first work in the lead to a transfer position and making it move in a work conveying direction of a second conveying device as much as the specified pitch, while situating a second work in a position as far as one pitch rearward to the first work. CONSTITUTION:A work 1 conveyed to a takeout position P by a first conveying device 10 is carried to a receiving position Q by a second hanger conveyor 18 and successively transferred to an discharge position (q) by a transfer truck mechanism 16. Almost simultaneously with this operation, a succeeding work 2 is fed to the position P of the device 10, and this work 2 is carried to a rear part B and an outer side N of a second conveying device 11 from the position P by the conveyor 18. During this operation, the device 11 stops, and when receipt of these works 1 and 2 is over, the device 11 makes these works 1 and 2 go forward as far as two pitches and parts other than a front part A and the outer side N of a receiving part R are emptied, and afterward, the same operation is repeated, thus these works are transferred onto the device 11 without disturbing the order.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is directed to a workpiece conveyance method suitable for plating processing equipment, etc., and in particular, a transfer method for transferring a workpiece from one conveyance device to another conveyance device. Regarding the method.

(Prior art) In general, in plating processes, etc., the first
and a step of installing the second conveying devices parallel to each other and with the conveying directions reversed, and transferring the workpiece (unprocessed material) from the first conveying device to the second conveying device in the horizontal direction (perpendicular to the conveyor conveying direction) ( Transfer process) may be provided. In such a process, the first MII transport device may transport the workpieces in one row, and the second transport device may transport the workpieces in two rows.

(Problem to be Solved by the Invention) However, according to the conventional transfer method, the workpieces that have been successively transported by the first transport device are transferred two by two to the second transport device in the reverse order of front and back and left and right. . Therefore, when a plurality of types of workpieces are continuously conveyed and different processing is performed on each workpiece, there is a problem that the processing after the 2111th feeding device is likely to be confused.

(Means for Solving the Problems) In order to solve the above problems, the present invention transports a large number of works to a take-out position by a first transport device, and transports the works from the take-out position to a second transport device by a second transport device. 'vf1 Transfer two workpieces from the side entrance side of the transfer device, and transfer the workpieces transferred from the first transfer device to the entrance side and the original population side at a predetermined pitch by two in total.
In a workpiece transfer method in which pieces are lined up one by one and transferred by a second transfer device in the opposite direction to the first transfer device, the first workpiece at the head of the first transfer device is transferred to the transfer position between the two transfer devices at the take-out position. The second work is taken out and moved by the predetermined pitch in the work transport direction of the second transport device, and the second work that has reached the take-out position next to the first work is taken out from the first transport device, and the first and second works are removed. The first workpiece is transferred to a second transport device, and in the second transport device, the first workpiece is located on the entrance side, and the second workpiece is located on the native population side and behind the first workpiece by one pitch. There is.

(Function) According to the above method, the first workpiece that has reached the takeout position of the first transport device is taken out to the transfer position and moved in the workpiece transport direction of the second transport device.

Next, the second workpiece that has reached the takeout position of the first conveyance device is taken out to the transfer position, and at the transfer position, the first workpiece and the second workpiece are lined up one after the other along the conveyance direction of the second conveyance device. In this state, the first and second workpieces are transferred to the second transfer station, and are lined up one after the other in the second transfer device, that is, in the same order as the first transfer device.

(Example) In FIG. 1, which is a schematic plan view, the first conveying device 10 and the second conveying device 11 are each constituted by a horizontal conveyor, and are parallel to each other and in the conveying direction G.

It is installed with F reversed. First transport device! ! 10 carries workpieces 1, 2, 3, 4, etc. in one line. The second transport device 11 is configured to transport two works 1, 2, 3, 4, . . . in parallel in the lateral direction (width direction of the second transport device 11). In other words, the second conveyance device 11 transfers the workpieces 1.2.3.4 on the inside M near the first Wi conveyance device 10 and the outside N away from the first Wi conveyance device 10.
It is designed to carry...

A transfer position T is located between the two transport devices 10 and 11. A transfer trolley mechanism 16 is provided at the transfer position T, and a first hanger conveyor 17 that connects the transfer trolley mechanism 16 and the second conveyor 11, as well as 1111th conveyors a10 and M2.
A second hanger conveyor 18 connecting the M feeding device 11 is also provided. The second hanger conveyor 18 is the first conveyor 10
Workpiece 1.2.3.4... which reached the removal position fffP of
can be transferred to the receiving position Q of the transfer trolley mechanism 16, or to the rear B and outside N of the receiving position R of the second transport device @11. Transfer trolley machine 4fli1
6 moves the work 1, for example, which has been moved to the receiving position EQ, forward by one pitch L in the transport direction F of the second transport device 11, and moves it to the discharge position Nq. The first hanger conveyor 17 is configured to transport, for example, the workpiece 1 from the discharge position q to the front part A and inside M of the receiving position R of the second conveying device 111.

With the above device, the workpieces 1, 2, 3, 4... are transferred to the first conveying device! It is transported from i10 to the 211th transport N11.

The workpiece 1 carried by the first transport device 10 to the take-out position 11P is carried by the second hanger conveyor 18 to the receiving position NQ, and then by the transfer cart mechanism 16 to the discharge position l! Transferred to q. Before and after this transfer operation, the first transfer device 21
The next work 2 is sent to the take-out position lfP of 0. This work 2 is transferred from the take-out position P to the second hanger conveyor 1.
8 to the rear B and outside N of the second conveying device 11. In parallel with this transfer operation on the outside N, the work 1 is transported by the first hanger conveyor 17 from the discharge position IWQ to the front part A and the inside M of the second transport device 11. During this operation, the second conveyance device 11 is stopped, and as described above, the workpiece 1
．． 2, the second conveyance device 11 moves the workpiece 1.2 forward by 2 pitches (2L: twice the distance between the front and rear of the workpiece 1.2) to the front part A and outside N of the receiving position tlR.
The remaining areas are emptied, and the same operation is repeated thereafter.

Next, the specific structure of the device of the embodiment will be explained.

As shown in FIG. 2, which is an enlarged partial view of I-[arrow in FIG.
